During the Great Depression, wretched labor camps crop up in remote areas of the expansive pine forests throughout the American South. Destitute workers live and toil under terrible conditions to harvest pine gum, hacking into tree trunks, drawing out the sticky sap that gives the Tar Heel State its nickname, and hauling it to stills to be refined into turpentine. Subsistence living means racking up huge debts they are forced to work off, creating an endless cycle of labor and debt. But for the most desperate among America's vast unemployed, these camps are often the last and only option.
